Lua UnPack函数用法实例

unpack它接受一个数组(table)作为参数，并默认从下标1开始返回数组的所有元素，例子代码如下：

do
 arraydata = {"a", "b", "c", "d", "e"};

 function returnmorevalues()
  return 1, 2, 3;
 end

 a, b, c = returnmorevalues();

 --print(a, b, c);

 --print((returnmorevalues()));

 --print(arraydata); -- print the address of the arraydata
 --print(unpack(arraydata)); -- print all the elements of the arraydata
 print(unpack(arraydata, 2)); --the second param is the index of the arraydata

end
